BASF is the current licensee of novel herbicide-resistant rice varieties developed by the LSU AgCenter to help control yield and quality reducing red rice as well as other important rice weeds. These varieties are commercially known as Clearfield Rice and were initially licensed to American Cyanamid Corporation before the company was acquired by BASF in 2000. The genetic technology that creates the resistance was developed by Timothy Croughan at the Rice Research Station. Steve Linscombe, and others at the Station, helped breed the actual rice varieties containing the gene. The varieties were designed to be resistant to imidazolinone herbicides, two of which are imazethapyr and imazamox. These two BASF herbicides can eliminate both red rice and conventional rice and are used commercially with the technology in the U.S. The AgCenter rice varieties can survive imidazolinone treatments while red rice will be eliminated. Horizon Ag, a major seed marketing group, has assisted BASF in the further development and marketing of Clearfield varieties, while others groups, such as RiceTec, have developed hybrids that also return royalties to the LSU AgCenter. These varieties to date have had tremendous success and have brought in millions of dollars for the university.
